How we worked it out

Calcium

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 800 mg = 24 g
  • £4.99 ÷ 24 g × 500 mg = 10.4p per 500 mg calcium
  • A week 10.4p × 7 = 73p · a month × 30 = £3.12 · a year × 365 = £37.94
  • Amount per serving: stated on the label.

Magnesium

  • Servings: 90 ÷ 3 per serving = 30
  • In the pack: 30 × 375 mg = 11.3 g
  • £4.99 ÷ 11.3 g × 100 mg = 4.44p per 100 mg magnesium
  • A week 4.44p × 7 = 31p · a month × 30 = £1.33 · a year × 365 = £16.19
  • Amount per serving: stated on the label.
